The funnel shapes of Crinum macowanii flowers taper with ridged surface into their green pedicels. This plant often has pink central bands down the white outside surfaces of the tepals and elaborately recurved tepal tips. The white or pink-tinged filaments curve up abruptly near their tips where they attach to the anthers, their long straight bodies emerging from the flower base.
These spectacular lily flowers grow in an easterly summer rainfall region of southern Africa, deciduous in winter (Manning, 2009).
